Near inertial oscillations in Lake Vänern
This is a suggestion for a Degree Project for Bachelor's and Master's levels at the Department of Marine Sciences. Degree projects at the Department of Marine Sciences are done independently and must be written and assessed individually.
Subject: Physical Oceanography
Main supervisor: Göran Broström, professor
Suitable time period: all year round
Suitable level and length: Bachelor or Master, project can be adjusted to suitable education level. At MSc level, designing and carrying out GCM experiments should be considered.
Location: Göteborg
Background
Lake Vänern is the largest lake in Sweden. It is quite deep at parts but has a complex geometry. Some new observations on thermal structure (moorings) shows presence/strong indication of large internal waves having frequencies close to the rotational frequency. It was a somewhat surprising result from a recent observational study.
The present project aims at studying those observations in greater details. For instance, will existing Ocean General Circulation (GCM) models for lake Vänern display similar waves.
Project description
The student will analyze newly taken observations from lake Vänern e.g. with respect to dominating frequencies in the spectral analysis of the time series. The student should also make literature studies for putting measurement into a broader perspective.
There exist a high-resolution ocean model for lake Vänern, and part of the investigation is to seek for similar waves in the Vänern GCM runs.
Method
The method will be analytical and numerical analysis of time series that is available. Literature studies will be required, as well as analysis from a GCM output.
